LIGHTING-FIXTURE.

Specification of Letters Patent.

Patented May 27, 1919.

To all whom it may concern:

Be it known that I, EDWIN F. GUTH, a citizen of the United States of America, residing at the city of St. Louis, State of Missouri, United States of America, have invented a certain new and useful Lighting- Fixture, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawinglsl, forming part of this specification.

y invention relates to lighting fixtures, and particularly to improved supporting means for the parts of those types of fixtures which embody an upper canopy or reflector, and a bowl, reflector or other light controlling or directing device beneath the canopy. In fixtures of this type there is usually a certain preferred relative position of lamp filament and upper and lower light controlling members, and the lamp receptacle is usually supported in fixed relation to the member which supports the upper reflector. Since electric lamps of different candle power usually dilfer in size, and there may be difierences in filament position in different lamps of the same size, supporting, devices which maintain the bowl in definite relation to the upper reflector can establish the proper relative positions for one size or design of lamp only.

One of the principal objects of my invention is to provide supporting means for the parts of the above mentioned types of fixtures, whereby the upper and lower light controlling members may be readily adjusted to proper relative positions for different sizes and designs of lamps. Other objects and advantages will appear from the following more detailed description.

In th accompanying drawings, Figure 1 illustrates a fixture embodying my invention; Fig. 2 is a top plan view of the main supporting tripod of this fixture; and Fig. 3 is an enlarged detail view of one of the supporting structures for the upper and lower light controlling members illustrated in Fig. 1.

1 represents a ceiling, in which is contained the usual junction box 2. Supported from this junction box 2 is the main fixture supportin member or tripod 3, to which is also attac ed a lamp socket 4:. The cano y reflector 5 is supported from the arms of t e tripod by the threaded members 6, provided wlth bearing heads 7. As shown, the length of the arms of the tripod is so chosen with respect to the depth of the canopy that they terminate short of the interior lower surface of the canopy. When the lower edge of the junction box is flush with the ceiling line and the portion of the ceiling embraced by the canopy, all lies in a single plane. Th1s construction permits adjustment of the canopy to cause its edges to rest upon the celling, even though the junction box is not set exactly at right angles to the ceiling, or protrudes therefrom, or the portion of the ce1l1ng at the junction box is not in the plane of the portion upon which the upper edge of the canopy bears.

As shown, the supporting members 6 have a central opening into which the bowl support ng spindles 8 extend, these spindles bemg 1n threaded engagement with the heads 7 of the members 6.

It is generally preferred to have the lamp filament 9 situated slightly below a line includlng the upper edge of the bowl 10 and the outer edge of the lower reflecting surface of the canopy 5, and the construction described makes it possible to readily establish this relation for a variety of sizes and types of lamps, which may be inserted in the socket 4, and the necessity of modifying the relatlve sizes of canopies and bowls for dif ferent s1zes and types of lamps is avoided.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a lighting fixture the combination of a main support suitably attached to the ceillng, a canopy-reflector carried by said maln support and vertically and angularly adjustable with respect thereto, a light controlllng device below the canopy, and means comprlsmg a part of the canopy supporting means for adjusting the controlling device with respect to the canopy.

2. In a lighting fixture, the combination of a main supporting member suitably attached to the ceiling and having depending arms, a canopy supported therefrom and adjustable with respect thereto, a bowl or other light directing or controlling device below the canopy, and means for vertically adjusting said bowl with respect to said canopy.

3. In a lighting fixture, the combination of a junction box, a main supporting member attached thereto and having depending arms, a canopy, a bowlor other light directing or controlling'device below the canopy, canopy supporting members each connected; with an arm of the main support and verti-V cally adjustable, with respect thereto, and

bowl supporting members in adjustable engagement with the canopysupporting members whereby the position of the bowl with respect'tothe canopy may be varied.

4. In a lighting fixture, the combination of a junction box, a main supporting member attached thereto and hax' ing depending arms, a lamp reoeptaclesupported in fixed relation thereto, acanopy, a'bowl or other light directing or controlling device below the canopy, canopy supporting members havingthreaded connection withthe arms of the main support and adapted to vary the bowliwithrespect to the canopy may be varied, said canopy supporting members having a central openingto receive/the ends of the bowl supporting members.

In testimony whereofI'ha ve hereunto set I my hand and: affixed my seal. p
